Application filed October 18,1907.

To all whom it may concern:

Be it known that I, Erwin Sf KiNTZ, a citizen oi the United States,residing at kenmore, in the county. of Summit and State of ()hio', haveinvented new and useful linprovements in Vehicle-Wheels, of which thefollowing is a specification,

This invention relates to vehicle wheels provided with pneumatic, solidor cushion tires of elastic material, more particularly pneumatic tiresof the double tube type having contractible, inextensible orsemiinextensible beads or edges, and the object thereof is to soconstruct the wheel as to enable the tire to be quickly applied orremoved when necessary.

The invention further aims to provide a wheel of the class referred towith a. new and improved holdfast means for the tire, hereinafter morespecifically described, said means. 'hxedly securing the tire H1position so that the same will not be displaced in any manner and studmeans being readily removable to permit oi the mounting and disniountingof e tire on said wheel.

1 V ihe invention iurther arms to PIOVIUO a vehicle wl'ieel of the classreferred to with 2.

new and improved rim, hereinafter more speciiicalh described, said rimcooperating with the holdlast menus for the tire, said rim and meansbeing simple in construction, strong, durable, elhcicnt in use,inexpensive to manulacture, readily applied to wheels and enabling atire to be readily removed when ocl c: sion requires.

(lther advantages constituting objects of this invention will more lullappear in the suhjoincd description.

A practical embodiment ol' this invention is illustrated in theaccompanying drawings in which similar reference numerals indicate likeparts in the ditl'erent ligurcs.

in the drawings, l igure l is a cross-scctionnl and perspective view ofa rim and tire portion of n. \VllO-( constructed in nccordznice withthis lTlVQlllilOll, also showing the holdf last menus lor securing thetire, said holdl astmeans arranged in operative relation with respect tothat form of tire known as the clencher type; Fig. 2 is a side elevationof a ring employed in this device; and, Fig. 3 is a view similar to nig. 1 showing the means for i securing the locking ring in position.

lielerring to the specific form of wheel shown in the drawings, 1denotes e llet rim Specification of Letters Patent.

; having one side formed with an endless outwardly-extending flange 2forming an abut ment to receive the rebbeted outer portion of an endlessannular tire-holding menus 3 arrangedto be mounted on the rim '1 and beheld from lateral movement by means of the flange 2. Also mounted on therim 1 a second tire-holding device 4 constructed like the tire-holdingmeans 3. The tire-holding devices 3 and 4 in cooperation with the rim 1constitute a. channel or tire sent in which is mounted a clencher typeof tire comprising an outer casing 5 and inner tube 6 constructed in theordinary manner. The opposite side of the rim 1 from that on which isformed the flange 2 is provided with an inwai' lly--e:'- tending ordepending llange 7, both for the purpose of strengtl'iening the rim aswell as to serve as a guide for a locking ring used for lateraldisplacement when the tire is inflated. Atv preferably regularlyrecurring intervals throughout the entire rim and slightly spaced fromthe flange 7 are a plurality of slots :2

in Fig. 2 and rel'crrcd to by the reference nu- Eh) meritl 9, which isarranged to vent therein. 'lhis locking ring it is provided on its outcrperiphcr with a pluralitr ot' pict'cruhly rogulerly-recurring lugs orteeth to the spuccs l spaces between the openings or slots 8 in the thechannel 20 betii'een the flange 7 and the folly of the wheel the lugs orteeth to will and cmrstitnte stops or abutments for preventing latcralmovement of the tire-holding device 4. ln order to place this ring S)in. the channel it is broken or split at a point indicated by thereference numeral 12 which to teeth 10. The faces of the ring at thepoint i of severance are preferably inclined lor pur pose to behereinafter set forth.

1 preferably occurs between two of the lugs or t 1' ln setting up wheelin connection with this invention, 11:.

maintaining the tire-holding device t from 75 openings 8 formed entirelythrough the llttl l ot a 83 intervening between them being count to theoff rim, so that when the ring ll is mounted in project outwardlythrough the openings h 1' the tire-holding device 3 is slipped sidewiseonto the rim 1 until this rabbeted portion engages the flange 2. This isfollowed by the tire, in a deflated condition, and this by thetire-holding device 4. It will be noted-in doing this that as the tireis deflated, the tireholding device 4 can be pushed toward the lateraltransverse center of the rim sufficientlyfar'to leave the openings orslots 8 unobstructed and the ring 9 is then sprung into the channel 20formed by the depending flange 7 and the side of the telly 11,-in doingwhich the ring is so positioned that the teeth 10 will be in radialalinement with the openings S and will project tl'ierethroughsufliciently-to constitute stops or abutments tor the tire-holdingdevice 4, thereby preventil'ig the same being slid. laterally from offthe rim. This ring is so made as to be self-expansible and it thereforeretains itself in position and the teeththereof' project from theopenings 8 by reason of its own inherent resiliency. This tendency ofthe ring to be self-maintaining is also aided by the fact that when thewheel is revolving at a high speed the centrifugal action set up bvthemotion of the wheel causes the ring to hug the bottom of the channel 20.

In order to permit the sliding of a tire onto the rim 1. when the tireis provided with an inflating tube, a transverse slot 13 is cut into therim 1 from the side which bears the tlange 7 and a corresponding slot 14cut in the folly, so that the inflating tube will olfer no ohstructionto the passage of the tire onto the rim. EXPOIlGHCO has demonstratedthat it will he sometimes necessary to employ other means formaintaining the locking ring 9 in its expanded condition than its ownresiliency and the centrifugal action developed by the revolution. ofthe wheel; and hence a keeper 15 is preferably provided which isarranged to be pivoted on a bolt 17 and held in operative position by aholdfast device such as a pin or bolt passing througl'i a perforation 18in its opposite end which engages in a corresponding opening 19 in theside of the felly. This keeper is provided on one face with awedge-shaped portion :10, for a purpose to be stated. When the keeper 15is used it will be preferably so positioned as to close the slot 14 cutin the folly when in its operative position and the locking ring S) willbe so placed that the broken portion thereof will also be opposite thisslot. Thus the keeper will act a closure device for the slot forpreventing the entrance therein of foreign substances. When the lockingring is seated properly in the channel, the keeper is swung upwardlyinto its operative position causing the wedge-shaped portion 16 to enterthe space between the inclined ends of the broken ring, therebyexpanding the same and cansing the teeth 10 to interlock more firmlywith the rim 1. The action of the keeper 15 is to expand the ringcircumferentially and as the amount of expansion is limited by thebottom of the channel 20, the ring itself is securely locked againstdisplacement. l/Vhen the keeper is in its operative position, a holdfastdevice is inserted through the opening 181 into the opening 19 made toreceive the same and the keeper itself is fixedly secured in position.In order to dismount a tire from a rim of this construction, the keeperis swung into its inoperative position, shown in Fig. 3, the lockingring 9 sprung from its seat in the channel 20, the tire-holding device4withdrawn sidewise from the rim and the tire slid laterally from itsseat.

It will be obvious that it is entirely within the scope of thisinvention to make the tireholding means 3 and the flange 2 integral withthe rim 1, thereby reducing the number of parts, this being done bysimply bending upward and inward the side edge of the rim and it will beapparent that the same results will be accomplished if the rim is madein this manner as if it were made in the manner heretofore described.

Having thus described my invention, What' I claim and desire to secureby Letters Patent, is r l The combination in a vehicle wheel, of a follyand rim forming a tire seat mounted thereon provided with aninwardly-extend.- mg flange spaced apart from said felly to form anannular channel, said rim being further provided with a plurality ofalined openingsin open co'nnnunication with said channel, a tire-holdingdevice mounted on said rim, and a self-'expansible ring in said channelcarrying means arranged to extend tl'irough said openings and constituteabutments for preventing lateral displacement of a tire-holding devicemounted on said rim.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witlICvS'SGH.
